Definitions

  • This invention relates to an image processing machine equipped with document scanning means and/or image forming means.
  • the document scanning means optically scans a document to be converted into a transmission signal or copied.
  • the image forming means forms an image on a printing substrate according to the received signal or to the optically scanned document.
  • An image processing machine such as a copying machine, a printing machine, or a facsimile machine capable of functioning as a copying machine or a printing machine is equipped with the document scanning means and/or the image forming means.
  • Document scanning means for optically scanning a document which have so far been proposed and gained commercial acceptance are of the stationary document placing stand type, the movable document placing stand type or the sheet-like document conveying type.
  • document scanning means of the stationary document placing stand type the document is placed on a transparent plate of the stationary document placing stand, and scanned by moving movable optical means along the transparent plate.
  • document scanning means of the movable document placing stand type the document is placed on a transparent plate of the movable document placing stand, and scanned by moving the movable document placing stand across a scanning zone in which stationary optical means is in action.
  • a sheet-like document conveying passage is provided extending across a scanning zone in which stationary optical means is in action, and the sheet-like document is scanned by conveying it through the conveying passage.
  • the document scanning means of the sheet-like document conveying type can automatically scan a number of sheet-like documents more easily and rapidly than those of the other two types, but cannot scan documents of other shapes such as a book.
  • the document scanning means of the stationary document placing stand type or the movable document placing stand type can scan various types of documents including a sheet-like document and a book. It has therefore been desired to develop document scanning means which functions not only as the sheet-like document conveying type but also as the stationary or movable document placing stand type.
  • Patent Abstract of Japan Vol. 9, No. 102 (E-312) (1825), May 4, 1985 discloses a reader featuring document scanning means of the sheet-like document conveying type and the stationary document placing stand type combined in one apparatus.
  • the object of this invention is to provide an image processing machine equipped with document scanning means of the movable document stand type and the sheet-like document conveying type having safety characteristics to prevent injury to the operator's hand or damage to a document when the operation of activating the scanning means of the sheet-like document conveying type is confused by error with the operation of activating the scanning means of the movable document placing stand type.
  • FIG. 1 shows an image processing machine embodied as a facsimile machine capable of functioning as a copying machine.
  • the illustrated image processing machine has a nearly rectangular parallel pipedal housing 2.
  • Document scanning means shown generally at 4 and image-forming means shown generally at 6 are mounted on the housing 2.
  • control means 8 for controlling the actions of various means in the image processing machine and the transmission and receiving of image signals when the image processing means functions as a facsimile machine.
  • a detailed description of the control means 8 itself is omitted in the present specification because it has nothing directly to do with the novel features of the image processing machine of the invention.
  • the document scanning means 4 will be described in detail with reference to Figure 1.
  • An opening extending in the widthwise direction (the direction perpendicular to the sheet surface in Figure 1) is formed at a predetermined site on the upper surface of the housing 2, and a first scanning zone 10 is defined by the opening.
  • a second scanning zone 12 defined by a widthwise extending transparent plate (or slit) is disposed in the left side portion of the inside of the housing 2.
  • First document illuminating means 14 is disposed within the housing 2 in relation to the first scanning zone 10, and second document illuminating means 16 is disposed in relation to the second document scanning zone 12.
  • the first and second document illuminating means 14 and 16 include suitable lamps extending in the widthwise direction such as halogen lamps.
  • Image-receiving means 18 is disposed nearly centrally in the housing 2.
  • the image receiving means 18 may be constructed of a known optical reading device composed of an array of many suitable solid image pick-up elements such as CCD (where it is not necessary for the image processing machine to function as a facsimile machine, the image receiving means 18 may be comprised of an electrostatographic material used in ordinary copying machines).
  • optical means shown generally at 20 Within the housing 2 is also provided optical means shown generally at 20.
  • the optical means 20 comprises a light path changing reflecting mirror 22, a first stationary reflecting mirror 24, a second stationary reflecting mirror 26 and a lens assembly 28.
  • the light path changing reflecting mirror 22 is selectively held at a first position shown by a solid line and a second position shown by a two-dot chain line.
  • the first scanning zone 10 When the light path changing reflecting mirror 22 is held at the first position, the first scanning zone 10 is optically connected to the image receiving means 18 via the light path changing reflecting mirror 22, the first stationary reflecting mirror 24, the second reflecting mirror 26 and the lens assembly 28. On the other hand, the light path between the second scanning zone 12 and the first reflecting mirror 24 is shut off by the light path changing reflecting mirror 22, and therefore, the second scanning zone 12 is not optically connected to the image receiving means 18.
  • the first scanning zone 10 fails to be connected optically to the first reflecting mirror 24 by the light path changing reflecting mirror 22, and consequently, the first scanning zone 10 is not optically connected to the image receiving means 18.
  • the light path changing reflecting mirror 22 recedes from the light path between the second scanning zone 12 and the first reflecting mirror 24 and the second scanning zone 12 is connected optically to the image receiving means 18 via the first reflecting mirror 24, the second reflecting mirror 26 and the lens assembly 28.

Conveniently, the width-restricting members 58 and 60 are moved simultaneously in a direction in which they come close to each other and in a direction in which they move away from each other. As will become clear from the description given hereinafter, the left side surface 56 and the pair of width-restricting members 58 and 60 function as a document insertion guiding passage for sheet-like documents to be conveyed through the second scanning zone 12. Furthermore, to the document cover 36 is fixed a sheet-like document supporting plate 66 having an upper surface which follows the left side surface 56 and extends inclinedly upwardly to the right.
